What carburetor do I have?

[DMackLewis]

I recently acquired a very tired 1955 C-3-PW from out of state. When I got it home I found that instead of a T137 engine it had a late T214 from a WC 3/4. I am now trying to id the carburetor. It is a BB Carter but not an ETW1. Does anyone know of a source with photos that might help me or perhaps someone can tell from the attached images.

Here are a couple sources that may or may not help.

It looks to be a Carter E7T2
One of the correct Carbs for the 55 C3 PW.

Thanks for the replies.

http://www.carburetor-parts.com/ helped me know here to look for the model number and what the structure is.

It's a 2681s and http://www.thecarburetorshop.com/Carburetor_ID.htm tells me that it's for a 1957-1960 Dodge D-series truck among a great number of other applications.

Externally, the 2681s and E7T2 look identical to me. I wonder what the actual difference is?

I would think this carb has a mechanical accelerator pump. That is an improvement over my 1952 PW with the vacuum type acc pump (E7S2).
Maybe Tom would know for sure?

The vacuum ones tend to hesitate on acceleration. Also pumping the accelerator pedal before starting does help much.
